Umbilical arterial (UA) Doppler assessment is used in surveillance of fetal well-being in the third trimester of pregnancy. Abnormal umbilical artery Doppler is a marker of uteroplacental insufficiency and consequent intrauterine growth restriction (IUGR) or suspected pre-eclampsia.
1 Umbilical vessels are relatively accessible in the newborn infant, particularly the very small and very large infants. 2  As a general rule, infants less than 1000g should have an umbilical venous catheter (UVC) inserted on day 1. 3  Larger infants with significant respiratory distress may also require a UAC.
